Contract Killer

Contract Killer is one of those games you try out once and never put down again for a very long time. In the game you play, well, a contract killer. As an assassin you take hit assignments initially for the government but fall from your superiors graces and end up taking assignments from various shady people. Some people might get bothered by the game premise, but it's still a very addictive game to play. It was created by Glu Games, Inc., who promises to keep updating the game and adding more content and levels while keeping it all free.

NinJump HD

Who doesn't love ninjas? With their stealthy black masks and lighting quick reflexes, it's hard to resist a cool game with them on especially if it's offered for free. Take NinJump HD for instance. This stunning and fast paced game puts you in control of this masked, sword wielding hero. Your main task is simple, you just have to climb a wall as high up as you can go. Despite the simple gameplay, the game is one that's hard to put down. It was developed by Backflip Studios, a company who seems to have a knack for making even the simplest, most mundane game premises quite addictive. They're the same geniuses who gave us Paper Toss: World Tour and Ragdoll Blaster 2.

Poton

Are you a fan of the Bomberman series? Poton gives you something to be happy about if you are. This cool, Japanese arcade game features a similar gameplay to classics like Pacman or Bomberman. Playing it will definitely bring in a lot of nostalgia for most old school gamers. Like most classic games, this one has a very simple gameplay to master. It basically consists of you being inside a maze and doing what you can to kill off the enemy one by one. The game has a very entertaining and quite addictive gameplay; a feature that most classic games have mastered.

Gun Bros

If you have an affinity for shooter games where you get to be the hero, shoot tons of bad guys and eventually save the day, Gun Bros is for you. The storyline isn't much, in fact, it's as predictable as can be. You're simply a gun toting special soldier who is bent on carrying your mission: "to protect the cosmos from the Tyrannical Oppressors of Life known as T.O.O.L." Armed with tons and tons of guns, you have to defend yourself against waves of enemies. They start off quite easy to kill but as you progress, you'll encounter bigger bad guys that'll test your skills. The game is offered absolutely free and plays on your iOs and Android devices beautifully.

Warthogs

Even though Harry Potter has officially ended, its legacy still lives on. Just take a look at the countless merchandise and spin-offs that remain. Speaking of spin-offs, Warthogs is one of the many tribute/parody games celebrating the story of the young boy wizard. The game was created by Crystal Shard and is a few years old but trust me, every second is still worth playing. In it, you play as Larry Lotter, a slacker who's about to take his final exam. The only problem is that Larry spent the entire night partying and is now late for class. Warthogs combines sarcasm with innovative gameplay and great graphics to bring you an exciting, almost offensive Harry Potter parody you'll certainly enjoy.

Stratus (Richard Edwards)

Another entry into what's now become a mecca of indie gaming goodness: Stratus is one of the hundreds of entries to the Ludum Dare game competition. Created by Richard Edwards, the game features interesting pixel style artwork and a pretty cool gameplay. For the uninitiated, Ludum Dare Competition has been around for years now. It's an event where independent gamers create an entire game in as little as 48 hours. Each game revolves around a certain theme that's announced before the start of the competition. For this one, more than 500+ entries have already been submitted, among them this cool puzzler from Edwards.

Candy Train

If you were into PopCap games back then, then you must have remembered Candy Train at some point. This simple but entertaining game was a staple on the PopCap roster. In fact, it was even available as a flash game on their website. Fast forward to now and this addictive game is available as a free download for the iPhone and iPad. The game was released under PopCap's "indie label," 4th & Battery where they promised to deliver edgier and experimental games. I'm not so sure if you can call Candy Train edgy or experimental but one thing's for sure, it definitely has the charm of a PopCap title: making you want to do nothing but keep playing.

iBall3D

iBall3D is actually the latest remake of the old classic game, Labyrinth. Instead of the old graphics, you get an updated gameplay and the game in full 3D. Gameplay is similar though; you need to guide a ball from one point of the map to another. The game was created by Stone Trip, and it features great graphics as well as excellent gameplay that will get players hooked into playing it. The perfect combination of puzzle solving and agility will ultimately help you to win this game. Give it a try. iBall3D works on the iPad, iPhone and iPod Touch. It's also available as a free download right under the Mac App Store.

eXtermination (Panic Arts)

There's nothing like a good zombie game to spend your afternoon's on and eXtermination is among the long list of such finds that's invading the indie gaming world for some time now. Created by Panic Arts, this zombie apocalypse is a horror platformer that incorporates great fun and interesting game play to create a more than just entertaining adventure. Being a fairly new game, it isn't perfect yet it still manages to engage gamers in a full-on entertaining zombie romp. With two game modes available, several weapons at your disposal and tons of zombies for target practice, this is quite a fun game to check out.
